You asked a question on your podcast about people using MSN search versus Google. One of the coolest features of MSN search (that almost no one knows about) is the RSS feed. When you do a search, at the bottom of the search results is an RSS button. If you subscribe to that, you can watch the top 10 sites for your favorite interest. When a new one comes on board it appears in your aggregator. I wish technorati had this feature.
